Final answer:
The primary goal of GWAS is to detect associations between single nucleotide polymorphisms (SNPs) and traits, especially diseases, by comparing the genomes of large groups of individuals.
Step-by-step explanation:
The primary objective of a Genome-Wide Association Study (GWAS) is c) Detecting associations between SNPs and traits. GWAS aims to identify differences among individual genomes, specifically single nucleotide polymorphisms (SNPs), which could be associated with various traits, including diseases. The procedure entails comparing two large groups of individuals, one with a specific disease and one without, to find SNPs that are significantly more common in the group with the disease. This can lead to the identification of genetic markers for disease susceptibility and provide targets for further research into the underlying molecular pathways and potential therapies.
